Summary

This chapter provides an overview of the consequences and impacts of 3D printing on architecture, structural design, society, the economy and the environment. The 3D printing of cement-based materials provides unprecedented freedom of form for architects and designers of concrete parts. The design of building and construction structures can be done using the concept of topological optimization. The new-found freedom of forms allows the design of structures to follow the intrinsic qualities of concrete (reduction of zones subjected to tension) and the reduction of the amounts of materials used. In addition, innovative reinforcement techniques will be tested and developed to work together with the printing process. Currently, research is carried out on the simultaneous printing of concrete and steel reinforcements. In order to provide the minimum tensile properties for cement-based materials, many studies have proposed the addition of fibers to the mixture for printing.
